## What it is
Drop is a JavaScript and CSS library for creating dropdowns, popovers, tooltips, and other floating elements attached to page elements. It is built on Tether.js for efficient, GPU-accelerated positioning that stays in view on scroll and resize.

## Use cases
- create dropdown menus attached to elements
- build popovers and hover cards
- add tooltips that stay in view on scroll
- position floating elements with GPU-accelerated animations
- open floating panels on click, hover, or focus
- nest dropdowns inside other dropdowns

## When to choose
- you need dropdowns or popovers positioned relative to target elements
- you want efficient repositioning on scroll and resize
- you need support for older browsers like IE9+
- you want a lightweight, MIT-licensed UI positioning library

## When to avoid
- you need a full-featured UI component framework
- you want a library with recent releases and active maintenance
- you need React or Vue-native popover components
- you require accessibility features beyond what the library provides

- artifact type: library
- maturity: maintenance
- function: ui-components, animation
